12-Lead ECG data acquisition system based on ADS1298

Abstract

A 12-lead ECG data acquisition system based on ADS1298 is presented in this paper. ADS1298 is a latest 16-channel 24-bit Analog to Digital Converter (ADC) made in TI Company, which has the characters of high-precision, low power and low noise, with the internal integration of the input multiplexers, analog low-pass filter, and digital filter, etc. Combined with the high-speed low-power chip M051 as MCU, it can achieve the standard 12-lead simultaneous ECG acquisition. ECG data can also be transmitted to an upper host PC though nRF24LE1 MCU. This system greatly compact the circuit and reduce the power cost, as well as implement the wireless transmission. It has laid the foundation for the future high-accuracy portable ECG instrument. © 2011 Published by Elsevier Ltd.
